When the procedures described in "7.1.6 Error History" are followed to display the error history, self-diagnosis of the
peripheral devices is also performed, and its results are indicated at the same time. The diagnostic items are:
1
Writing to then reading from the register of the AV decoder
2
Writing to then reading from the external SDRAM of the AV decoder
3
DMA transfer from the front end (EBY-CHIP) to the AV decoder
4
Writing to then reading from the register of the video encoder
